A revved up immune response, including for your respiratory system
Your immune system and gut microbiome (your gut’s ecosystem of more than 100 trillion bacteria1) are the ultimate duo. In fact, our gut accounts for about 70% of our whole immune system. That’s why feeding it with the highest quality probiotics is paramount to protecting your immune system against possible infections and cutting down just how long you’ll be sick too. (In one scientific review, kids and adults who took a probiotic supplement had “significantly fewer numbers of days of illness” and were absent from school less than those who took a placebo2.)
We chose Bifidobacterium lactis Bl-04 specifically because the research is aplenty—from proof that those who take Bl-04 have a faster immune response thanks to higher Immunoglobulin G levels3 to evidence that Bl-04 can help significantly reduce the risk of upper respiratory tract infections by 27%. Need more numbers? While the median time for the placebo group to get sick was 2.5 months, the median for those who took Bl-04 wasn’t until the 3.2-month mark4.
And not all Bifidobacteria are created equally—when comparing Bifidobacterium lactis Bl-04 to Bifidobacterium lactis Bi-07, and a placebo, researchers found that the risk of getting an upper respiratory illness was lower in the Bl-04 group4.
